Answer:
Irrational
Step-by-step explanation:
When we take the square root of both sides, we get z = 0.141421... and since there are no fractions and the decimals go endlessly on, it is irrational.
Find the vertex of the function given below y=x^2-2x+1
Hey there! :)
Answer:
(1, 0).
Step-by-step explanation:
Convert from standard form to vertex form by completing the square:
y = x² - 2x + 1
Move 1 to the other side:
-1 = x² - 2x
Complete the square. Remember to add to both sides:
-1 + (1) = x² -2x + 1
Simplify:
0 = (x - 1)²
The function in vertex form is:
y = (x - 1)²
Therefore, the vertex is:
(1, 0).
Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3.
Answer: - 4
Step-by-step explanation:
Given that A = - 4, B = 3
According to the instruction :
Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3
Raise - 2 to the double of b ;
Result = (-2)^(2*3) = (-2)^6 = 64
Divide result by quadruple of a
a = - 4 ;
Quadruple of 'a' means 4 times as many as 'a' = '4 * a' quadruple of a = (-4) * 4 = - 16
= (-2)^6 / -16
64 / - 16
64 / - 16 = - 4
The population of a large city can be calculated using the function . What can you say about the rate of change from year 1 to year 2 compared to the rate of change from year 9 to year 10
Answer:
The rate of change will be the same for all years.
Step-by-step explanation:
As it is mentioned in the question, that the rate of change is 7%.
And as we know that
= I (1 + R)^T
where
I = Initial amount
R = Rate of growth,
And T = Time.
So in the given case, the rate is 0.07, or 7% while on the other hand the growth RATE remains constant and the growing amount would be increased each year.
Therefore the rate of change would be the same for all the year

The length of the one of the legs of a right triangle is 8m and the hypotenuse is 12m
Answer:
other leg = 8.944271910
Step-by-step explanation:
If you are trying to figure out the other leg you have to use pythagorean therom:
c^2 - a^2 = b^2
(12)^2 - (8)^2 = b^2
144 - 64 =b^2
80 = b^2
√80 = b
8.944271910 = b
What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4=‐2/3(x-6) and passes through the point (-2, -2)?
y=-x-10
y=-2x19
y=x-1
y=x+1
Answer:
y=3/2x+1
Step-by-step explanation:
y-4= -⅔(x-6)
y-4=-⅔x+4
y=-⅔x+4+4
(equation of line 1) y= -⅔x+8 gradient= -⅔
(line 2)gradient=3/2
note* the gradients of perpendicular lines multiplied result to -1
gradient=y²-y²
x²-x¹
3 =y+2
2. x+2
multiply both sides by 2(x+2)to remove the denominators
3(x+2)=2(y+2)
3x+6=2y+4
3x+6-4=2y
3x+2=2y
divide all sides by 2
3/2x+1=y
y=3/2x+1
What is an equation of the line that passes through the point
(6,−2) and is perpendicular to the line
6x+y=2?
Answer:
y = 1/6x - 3
Step-by-step explanation:
Step 1: Find the slope
Take the negative reciprocal of the other slope
m = 1/6
y = 1/6x + b
Step 2: Find b
-2 = 1/6(6) + b
-2 = 1 + b
b = -3
Step 3: Rewrite perpendicular linear equation
y = 1/6x - 3
Trevor drew lines of best fit for two scatter plots, as shown. Which statement describes the placement of the lines Trevor drew?
Answer:
A)Only Line A is well placed line of best fit
Step-by-step explanation:
Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line
The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit
By considering both the given graphs
We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit
So,Option A is true
A)Only Line A is well placed line of best fit
Answer: a) only line A is a well placed line of best fit

Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30
Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Step-by-step explanation: 6(x+4)=30
(Distributive property): 6x+24=30
( Transposition method): 6x=30-24( + becomes -) 6x=6
(Transpose 6 to rhs) x=6/6( since it was multiplication on LHS it becomes division in RHS) x=1

24 athletes threw the shot put at a track and field meet. If this was 15/100 of all the athletes in the meet, how many athletes competed in the meet total?
Answer:
160 athletes
Step-by-step explanation:
Let the total number of athletes in the meet be x
Given that 24 athletes who threw the shot put at a track and field meet are 15/100 of all the athletes in the meet .
If we write this in mathematical algebraic expression
15/100 of all the athletes in the meet = 24
15/100 * x = 24
=> x = 24*100/15 = 24*100/3*5 = 160
Thus, 160 athletes competed in the meet.

ILL MARK BRAINLIEST In independent random samples of 10 men and 10 women in a coed basketball league, the numbers of points scored per season are given by the back-to-back stemplot below:
Part A: Describe the shape of each data set.
Part B: Michaela analyzed the data and stated that the better measure of center for the women is the mean. Is Michaela correct? Explain your reasoning.
Part C: Michaela decided there are no outliers in the women's data set. Is she correct? Justify your answer mathematically.
Answer:
Step-by-step explanation:
Hello!
a)
To compare both datasets I've made a box plot for them.
The yellow one belongs to the points scored by the men and the green one is for the points scored by the women.
Women: The box seems symmetrical, the median and the mean (black square) are almost the same. The whiskers are almost the same length, you could say that in general the points scored by the women have a symmetrical distribution.
Men: The box looks a little skewed to the right, the median is closer to the 1st quantile and the mean is greater than the median. The whiskers are the same length, in general the distribution seems almost symmetrical.
b)
As you can see in the box plot the median and mean of the points scored by the women are almost the same. Using the data I've calculated both values:
Me= 24.50
X[bar]= 23.80
The median divides the sample in halves (50-50), it shows you where the middle of the distribution is.
The average shows you the value that centers the distribution, meaning, it is the value around which you'll find most of the data set. It summarizes best the sample information and therefore is a better measure of center.
c.
As you can see in the box plots, there are no outliers in both distributions.
An outlier is an observation that is significantly distant from the rest of the data set. They usually represent experimental errors (such as a measurement) or atypical observations. Some statistical measurements, such as the sample mean, are severely affected by this type of values and their presence tends to cause misleading results on a statistical analysis.
Considering the 1st quartile (Q₁), the 3rd quartile (Q₃) and the interquartile range IQR, any value X is considered an outlier if:
X < Q₁ - 1.5 IQR
X > Q₃ + 1.5 IQR
Or extreme outliers if:
X < Q₁ - 3 IQR
X > Q₃ + 3 IQR
For the women data set:
Q₁= 17; Q₃= 30; IQR= 30 - 17= 13
Lower outliers: X < Q₁ - 1.5 IQR= 17-1.5*13= -2.5 ⇒ The minimum value recorded is 03, so there are no outliers.
Upper outliers: X > Q₃ + 3 IQR= 30 + 1.5*13= 49.5 ⇒ The maximum value registered is 41, so there are no outliers.
I hope this helps!

Answer:
10 cm
Step-by-step explanation:
Since WX is tangent, it is a right angle
VWX is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2
6^2 + 8^2 = VX ^2
36+64 = VX ^2
100 = VX ^2
Take the square root of each side
sqrt(100) = sqrt( VX ^2)
10 = VX
Answer:
10 cm
Step-by-step explanation:
Since WX is tangent to the circle V, by definition, WX ⊥ WV.
So, we've established that ΔWXV is a right triangle. This means that we can apply the Pythagorean Theorem, which states that for a triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, we have a = WV = 6 and b = WX = 8, so:
a² + b² = c²
6² + 8² = 36 + 64 = 100
c² = 100
c = √100 = 10
Therefore, VX = 10 cm.

If Milly has 29924827134702 candies and she gave 928439 to BOB then he gave 1000 back to Milly How much does both Milly and BoB have?
Answer:
"BOB" gave back 1000 that would be 928439 - 1000 = 927439(BOB has)
"BOB" gave back 1000 to Milly.. 29924827134702 + 1000 = 2.9924827(MILLY has)
Step-by-step explanation:
well, first, if "BOB" gave back 1000 that would be 928439 - 1000 = 927439, so "BOB" now has 27439. and now, "BOB" gave back 1000 to Milly sooo now it is 29924827134702 + 1000 = 2.9924827 (e+13) soooo ya thats it
